PIR wiring Help
I
am
trying to wire up a number of PIRs to a Linux box which has specific
digital
inputs similar to homevision.
All
works fine for a single PIR however I want to wire several on a single
input so
that any of the pirs triggering will trigger the input and also I want to
wire
the Tamper contacts in a similar way on a seperate
input.
For a
single PIR I have.....
Input
PIR
In+
to
C
+12
to +
GND
to
-
In- on
the input is linked to GND on the input
+
on
the PIR is linked is linked N on the PIR
and
finally there is a 10k resistor between - on the PIR and C on the
PIR
This
all works fine but can someone please explain how I add additional
PIRs?
Cheers
Mick
